What combination of DNSBL servers offers the most
protection? |
|
|
 |
Is one DNSBL server enough? Are six too many? |
|
|
 |
Where is the point of diminishing return reached? |
|
|
At a glance, the
BL-Monitor PRO Best Combinations Report answers these questions, presenting the
most efficient number of DNSBL servers to use for your email
filtering.
All guesswork is removed.
|
BL-Monitor PRO
performs this analysis upon completion of the DNSBL queries and for
the given number of servers provides the most effective filtering
combination. This analysis also
determines:
 |
How many IPs are uniquely
listed on a DNSBL server |
 |
How many IPs are listed as common on two or more DNSBL servers |
This quickly
determines if the addition of more
DNSBL servers is worthwhile and will improve email efficiencies.
